Apical hypertrophic cardiomyopathy mimicking acute myocardial infarction
1Division of Cardiology, Department of Medicine, Veterans General Hospital-Taipei, Taiwan.
Insights
A patient initially suspected of acute myocardial infarction was diagnosed with apical hypertrophic cardiomyopathy. This condition presented with an apical aneurysm and mid-ventricular obstruction, mimicking heart attack symptoms.
Area of Science:
- Cardiology
- Cardiovascular Imaging
- Internal Medicine
Background:
- Thrombolytic therapy is a critical treatment for acute myocardial infarction, characterized by ST-segment elevations on electrocardiograms.
- Accurate diagnosis is essential to differentiate acute myocardial infarction from other conditions presenting with similar symptoms.
Observation:
- A 77-year-old male presented with typical ischemic chest pain and ST-segment elevations, prompting emergency department evaluation.
- Initial assessment suggested acute myocardial infarction, leading to the administration of thrombolytic therapy.
Findings:
- Further hospitalization and diagnostic workup excluded acute myocardial infarction.
- The patient was diagnosed with apical hypertrophic cardiomyopathy, a condition characterized by left ventricular apical aneurysm formation and mid-ventricular obstruction.
Implications:
- This case highlights the importance of comprehensive diagnostic evaluation to avoid misdiagnosis of acute myocardial infarction.
- Apical hypertrophic cardiomyopathy with obstruction can mimic ischemic heart disease, necessitating advanced imaging and clinical correlation.
- Understanding these mimics is crucial for appropriate patient management and therapeutic decisions in cardiovascular medicine.
Abstract:
Thrombolytic therapy was given to a 77-year-old man with typical ischemic chest pain and unequivocal electrocardiographic ST-segment elevations at the emergency department. The diagnosis of acute myocardial infarction was excluded during hospitalization and the patient was found to have apical hypertrophic cardiomyopathy with apical aneurysm formation and mid-ventricular obstruction.
